Fascinating.
In this situation I find it useful to take a bird walk in the company of Bill
Google, as cage-bird hobbyists have more than their fair share of the graphic
space out there on the internet.
Yellow
mutations of the Turquoise Parrot are plentiful in collections. See 1a and
1b below, the first being the subject bird. I am not sure about 1c.
I, being no aviarist, suppose they are turqs, but they could be something
else. This is not entirely a matter without relevance to field
observations. Some years ago there was famous discussion about a turq
sighting at Jerra Wetlands where Joe Forshaw identified the bird as a ‘dilute
mutation’ on account of the yellow, which led to the bird being classed as an
escaper by the rarities committee. At Weddin Mts Richard Allen
occasionally nets a male turq with orange on the lower belly. This seems
to be a variation that occurs in the wild but whether related to the cagebird
mutation I do not know. In the well-known phrase of the field
guides: “Some birds have …”
What
yellow is to the turq, pink is to the Bourke’s Parrot. See 2, and take the
walk with Bill Google if you want to see more variations.
I
have no idea myself about the dark finch - 3. The bird seems
to be in moult, and possibly an immature. The Jacarina Finch Volatinia
jacarina aka Blue-backed Grassquit occurs over much of South
America.
I
thought Philip and Benj did well with what was offered.
